The machine which is shown in the drawings constitutes the preferredform or embodiment of the invention. It is primarily designed for I thepower mechanism back and forth between a normal operating position and adischarging position, and means 20 for'supplying the outer shell with awashing fluid, such as water, when the outer shell is in its normaloperating position.

The supporting structure I is adapted to rest on, and be 'flxedlysecured to, the floor of the laundry or other establishment in which thewashing machine is used. It remains stationary when in use and consistsof a pair of laterally spaced U-shaped standards 2| and 22 and aplurality of tie rods 23 between the two standards. The two standardsare positioned in horizontal alignment and embody base portions 24,upstanding front arms 25 and upstanding rear arms 26. They arepreferably in the form of metallic castings and have floor engaging feet21 on the bottom of their base portions 24. The tie rods 23 servefixedly to space apart the two standards 2| and 22 and have the endsthereof suitably secured to the arms and base'portions of the standards.In addition to the parts heretofore mentionedthe supporting structure l5comprises a horizontally extending shaft 28 and a bar. The shaft 23extends between, and is fixedly connected to; the upperextremitiesof'the front arms 25 of the two standards. The bar 29 is disposed inparallel relation with the shaft 28 and extends between, and is suitablysecured to, the upper extremities of the rear arms 26 of the standards2| and 22.-

The outer shell I6 is positioned between the U-shaped standards 2| and22 of the supporting structure l5 and embodies a cylindrical side wall30 and a pair of circular or disc-like end walls 31. As shown in Figure1 the end walls 3| are provided with inwardly extending annular flanges32 and these extend around, and are welded or otherwise fixedly securedto, the ends of the cylindrical side wall 30. In addition to the flanges32 .the end walls 3| are provided with centrally positioned bearings 33and exteriorly disposed cup-shaped housings 34. The bearings 33 aredisposed in circular holes 35 within the central portions of the endwalls 3| and have radially extending flanges 36 which are bolted to thehole defining portions of the end walls 3|. The housings 34 serve tohouse the bearings 33 and are positioned centrally with respect to theend walls.

-'I'hey overlie the standards of the supporting structure and have onthe free margins of their side walls radially extending flanges 31 whichfit flatly against, and are bolted to, the outer faces of the end walls3|. The outer shell I6 is adapted in connection with operation of themachine to be charged with water by way of the supply means 2|] andembodies'a dump valve 38 whereby the water may be discharged from theinterior of the outer shell at the conclusion of a washing operation:

The dump valve 38 is of any suitable variety or type and isconnected tothe bottom portionof the side wall 30 of the outer shell. The side wall,

aspen 3|| embodies in the front upper portion thereof a rectangularopening 39 and this is closed by a door 40. The latter is arcuate incross section and is mounted .by-way of arcuate end tracks or guides 4|in order that it may he slid upwards and circumferentially with respectto the side wall oi the outer shell into an open position wherein itexposes the opening 39 for clothes charging and discharging purposes.The lower marginal portion of the door is provided with suitable latchesfor locking the door in its closed position. The front central portionsof the inwardly extending flanges 32 on the end walls 3| are providedwith collar-like elements 42 and these surround the ends of the shaft 23of the supporting structure I5 and form pivotal connections for theouter shell whereby the latter is permitted to swing bodily upwardsthrough substantially an arc of 90 into a discharging position whereinthe opening in its side wall faces downwards, as shown in Figure 3. Theouter shell ends of the pins when the outer shell is in its normaloperating position. It is contemplated that the machine will be chargedwith the clothes and like articles to be washed while the outer shell isin its normal operating position and the power mechanism i8 is at rest.After charging of the machine the. mechanism I8 is set inmotion forclothes washing purposes. At the end of the clothes washing operationthe power mechanism I8 is stopped and the door 40 is slid into its openposition so as to expose the opening 39 in the upper front portion ofthe side wall 30 of the outer shell. a After sliding the door into itsopen position the outer shell is swung upwards and forwards into itsdischarging position wherein the opening 39 faces downward and permitsthe clothes and other articles to fall by gravity out of the outershell. After discharge of the clothes and other articles the outer shellis swung rearwards and downwards into its normal operating positionwherein it is supported as a result of the hooks resting on the innerends of the pins 43;

The inner shell I! is disposed concentrically within the outer shell l6and is adapted to hold the clothes and other articles during a washingoperation. It is driven or rotated as hereinafter described by the powermechanism 3 and con sists of a foraminous cylindrical side wall 45 and apair of circular or disc-like end walls 46. The end walls are positioneddirectly inwards of the .end walls 3| of the outer shell i6 and haveoutwardly extending flanges 41 which fit within,

and are welded or otherwise fixedly secured to,

outer shell. The cylindrical side wall 45 of the inner shell embodiesinwardly projecting longitudinally extending ribs 49 for clothestumbling purposes and has a rectangular opening 50. The latter is closedby a door 5| which is of arcuate aaoes cross section and has tracks orguides 52 at its ends in ordl r that it may be slid circumferentiallywith respect to the inner shell into an open position wherein it exposesthe opening 50. By reason of the fact that the side wall of the innershell is fora-minous the water in the outer shell is permitted to flowthrough the interior of the inner shell into contact with the clothesand other articles to be washed. In connection with charging of themachine the inner shell, after first opening the door 40 for the opening39 in the outer shell, is rotated until the opening 50 in the innnershell is in registry with the opening 38.

Thereafter the door 5| is slid into its open position and the innershell is charged with clothes and other articles to be washed. Uponclosing of the doors SI and an the machine is in readiness for a washingoperation.

The power mechanism l8 serves in connection with operation of themachine, to rotate the inner shell back and forth relatively to theouter shell and comprises a reversible electric motor 53 and speedreducinggearingbetweenthemotorand the inner shell. The electric motor 53embodies a conventional solenoid brake 54 and is mounted on a bracket 55on the housing 34 that is adjacent the stardard 2 l The speed reducinggearing constituting part oi the power mechanism l8 comprises a bevelpinion 55, a bevel gear 51, a pinion 58 and a gear'59. The bevel pinion56 is mounted on one end of the armature shaft of the electric motor 53and meshes with, and serves to drive, the bevel gear 51. The latter,as-shown in Figure 6, is mounted on the outer end of a horizontallyextending shaft 60 which is positioned in parallel relation with theaxis of the outer shell i6 and is supported by roller bearings 6|. Thepinion 58 is keyed or otherwise fixedly secured to the inner end of theshaft 60 and meshes with,'

and serves to drive, the gear 59. Such gear is disposed in the housing34 that is adjacent the standard 2| and has the hub thereof connectedfixedly to the outer end of the adjacent trunnion 48. The upper portionof the housing 34 that is adjacent the standard 2| embodies anenlargement 62 which serves to house the bevel pinion 56, the bevel gear57, the pinion 5B and also to support the bearings ii in which the shaft60 is journailed. When the machine is in operationthe electric motor 53is driven in one direction for a redetermined period of time and then inthe opposite direction for a like period and hence causes the innershell to rotate back and forth relatively to the outer shell. By reasonof the fact that the power mechanism I8 consisting of the reversibleelectric motor 53 and the speed reducing gearing between the motor andthe inner shell-is mounted in its entirety on the outer shell I6 itmoves bodily with the outer shell in connectionwith swing of the latterback and forth between its normal operating position and its dischargingposition and hence it is at all times in If operative or drivingrelation with the inner shell regardless of the position of the outershell.

The hydraulic system I 9 for swinging the outer shell I6 together withthe inner shell I? and the power mechanism I8 backand forth between itsnormal operating position and its discharging position, comprises a pairof cylinder and piston devices 63 and these are located directlyoutwards of the standards of the supporting structure I5 and consists ofcylinders 64 and pistons 65. The lower ends of the cylinders arepivotally connected to brackets 56 on the base portions 24 of thestandards in order that the devices 53 connection with upward orsubstantially an age of are permitted to swing laterally in parallelrelation with the standards. The brackets 88 are preferably in the formof metallic castings and project outwards and downwards from the baseportions of the standards. They embody horizontally extending lowerparts 51 and these, as best shown in Figure 6, embody pairs of spacedapart fixed bearings 58. The lower ends of the cylinders 54 are closedby fixed caps 59 which embody diametrically opposite pintles III. Thelatter. are joumalled in. the bearings 68 and together-with saidbearings form the pivotal connections between the cylinders 64 and thebrackets 55. The upper ends of the cylinders 64 are closed by means ofcup shaped caps II which are connected in place by screw threadconnections (not shown) and have centrally disposed stufling boxes (alsonot shown). The pistons 65 of the piston and cylinder devices aremounted in the cylinders 54 for longitudinal v sliding movement andembody fixedly connected upstandingpiston rods 12 through the stuflingboxes in the cup shaped caps II. The upper ends of the piston rods arepivotally connected to brackets 13 on the'central portions of thehousings 34 by means ofsleevelike elements I4 and pins 15. The brackets13 are suitably attached or connected to the central portions of thehousings 34 and carry the pins 15 so that they are in axial alignmentwith the trunnions 48 of theend walls of the inner shell II. Thesleeve-like elements I4 are fixedly connected to the upper ends of thepiston rods and are rotatably mounted on the pins 15, as shown in Figure6. When fluid under pressure, such, for example, as

oil, is introduced into the lower ends of the cylinders 54 whiletheupper ends of the cylinders are vented the pistons 65 together with thepiston rods 12 are caused to slide upwards and result in the outer shellI5 together with the inner shell I! and the power mechanism I8 beingswung upwards and forwards from its normal operative position into itsdischarging position. When oil rods 12 are slid downwards and cause theouter shell together with the parts associated therewith to swingrearwards and downwards into it's normal operating position wherein itis supported by way of the pins 43 and the hooks 44. In downward slidingof the pistons and piston rods the cylinder and piston devices 63 swinglaterally with the pintles 10 as articulation points. The stroke of thepistons 55 is such that the outer shell IS in connection with swingthereof, either into or out of its discharging position, swingsthroughout When the outer shell is in its normal operating position thetrunnions 48 are horizontally aligned with the shaft 28 and when theouter shell isin its discharging position wherein the opening in theside wall thereof faces downwards the trunnions 48 are verticallyaligned with said shaft '28. As a result of the fact that the trunnions48 are in alignment with the shaft 28 when the outer shellis in itsdischarging position the outer shell is in sub- In addition to thecylinder and piston devices 63 the hydraulic system I9 comprises a gearpump 16, a control valve 11 and a particular pipe arrangement wherebyoil under pressure may be which extend slidably ders,

It is of.

- conventional desi n and consists of a casing 18 and a, pair of meshinggears 19 in the casing. One of'the gears is connected for drive by -auni directional electric motor 88 which is mounted on the outer wall ofthe base portion 24 of the standard 2| and is supplied with current by apair of conductors 8| and 92. The conductor II groove I88 establishescommunication between the ports 91 and98. Theiswitch 83 for controllingoperation of the gear pump driving electric unidirectional motor 16 isdisposed in the lower portion 01 the case 94 and is positioned so thatthe push button 88 thereof is located under the collar I8I between thelower end of the lever I88 and the outer end of the plug stem 99. The'collar is provided at the bottom thereof with a flat I86 against whichthe switch button 88 abuts when includes a normally open switch 83consisting of a pair of fixed spaced apart contacts '84 and 85 and abridge 86 for the two contacts. The bridge v is urged away from thecontacts by a compression spring 81 and has a push button 68 whereby itwherein the land I84 closes the port 96 and the land I85 closes the port91. When the push button is in engagement with the flat'the switch 83 gis in its open position and the pump driving motor may be shiftedagainst the force ofthe spring into a closed position wherein it'crossconnects' the two contacts 84 and 85 and results in flow ofcurrent to the electric motor 88. When the switch 83 is in its closedposition the motor 88' operates to drive the gear pump 18. The casing 18of the pump includes an inlet 89 and an outlet port 98.

The control valve 11 is mounted on the'upper 88 is, therefore,inoperative. is rotated out of engagement with the switch When the flatI86 button 88 in connection with either clockwise or counterclockwiseswinging of the lever I88, the

collar I8I operates to depress the button and hence closes the switchand results in operation hydraulicsystem I9 for swinging the outer shellI extremity of the front arm of the standard together with the innershell and the power mechanism back and forth between its normaloperating position and its discharging position comprises pipes I81,|88, I.89, 8 III, H2 and 3. One end of the pipe I81 leads to the baseportion 24 of the standard 2| and the other endof the pipe I81 isconnected to the inlet port 89 in the casing 18 of the gear pump 16. Thebase portion 24 of the standard 2| is hollow and, as

' shown in Figure 5, forms a reservoir II4 for 2.

9| of the control valve 11 has four ports 95, 96,91

and 98; As shown in Figure 9,- the ports95 and 98 are formed in the sideportions of the casing 9|, are positioned one diametrically opposite theother and lead outwards from the cylindrical bore 93. The port 96 isformed in the upper portion of the control valve casing 9| andcommunicates with, and leads'outwards from, the bore 93. The

fourth port, i. e., port 91, is'formed in the bottom portion of thecasing 9|, communicates with the bore 93 and is positioned diametricallyopposite the port 96. The plug 92 fits rotatablyv in the bore 93 and hasat its outer end a stem 99 which, as shown in Figure 8, projects intothecup shaped case 94 on the outer end of the valve casing 9|.

body or column of oil. .Said other end of the pipe I81 is so positionedthat it communicates with the lower portion of the bodyor column of oilin the reservoir III. The pipe I88 extends between the gear pump 16 andthe valve 9 I. One end of the pipe I88 is connected to the outlet port98 in the gear pump casing 18 and the other end 'of-said-pi'pe isconnected to the port 95 in the casing 9| of the control valve 11. Thepipe I89 is connected to, and leads from, the port 96. The pipe H8 is inthe form of a branch pipe.. It is An'upstandi ng lever I88 serves asamedium for v rotating the plug 92. The lower end of the lever isdisposed in the case 94 and is connected to the outer end of the stem 99by a collar I8 I. As

shown in Figure 8. the central portion of the lever extends through anarcuate slot in the .annular cylindrical side wall of the case 94. Theplug 92 of the control valve embodies a pair of oppositely disposedarcuate grooves I82 and I83 and these are positioned in alignment withthe ports .in the valve casing and are separated by a pair of lands I84and I95. 7 when the lever I88 is positioned vertically in what may betermed a neutral position the landIIIl closes the port 96 and the landI85 closes the port v 91.

' two grooves are 'alsoarranged that when the lever is swung in acounterclockwise direction-from its The lands are arranged so that andhas its ends connected to the lower ends of the cylinders 64 ofthecylinder and piston devices 63. The pipe I II is connected to, and leadsfrom, the port 91 in the control valve casing 9|. The pipe I I2 is inthe form of a. branch pipe as shown in Figure 10. It is connected tothe'discharge end of the pipe III and leads to the upper ends of thecylinders 64. The pipe 3 serves as a return pipe and has one end thereofconnected to the port 98 and its other end leading into the reservoir II4 in the base portion 24 of the standard 2|. When'the valve controllinglever I88 is swung in a counterclockwise direction from its neutral orvertical position so as to cause the plug groove I82 to establishcommunication between the ports 95 and 96 and the groove I83 toestablish commun'ication between the'ports 91 and 98,

the switch 83 is automatically closed, as hereinf before pointed'outgandas a result sets in operation'the motor 88 which, in turn,drives the pump 16 sov that it supplies .oil under pressure into thelower ends of the cylinders 64 via pipe I88, port 95, plug groove I82,port 96, pipe I89 and branch pipe II8. As soon as the oil under pressureis introducedinto the lower ends of the cylinder 64 the pistons 65 moveupwards and operate through of the cylinders are vented and the oilabove the pistons flows back to the reservoir I I4 via branch pipe II2,pipe III, port 91, groove I03, port '98 and return pipe I I3. When thelever I is swung from its neutral or vertical position in a clockwisedirection as viewed in Figures"! and 10, so as to cause the plug grooveI02 to establish communication between the ports and 91. and the grooveI03 to establish communication between the ports 01 and 90, the switch83 is automatically closed and sets in motion the unidirectionalelectric motor 80 which in turn drives the gear pump I6 so that thelatter pumps oil under pressure into the upper ends of the cyinders 04via pipe I00, port 35, groove I02, port 91, pipe III and'branch pipe II2. Entrance of fluid under pressure into the upper ends of the cylinders64 of the cylinder and piston devices 63 results in the pistons 55sliding downwards and causing the outer shell I6 to swing rearwards anddownwards into its nor-.

mal operating position. During downward sliding movement of the pistonsin the cylinders the lower ends of the cylinders are vented and theoilbeneath the pistons flows back to the reservoir II4 via the branchpipe IIO, pipe I09, port 96, roove I03, port 98 and return pipe H3. Whenthe control lever I00 is in its neutral position wherein the lands I04and I05 close, respectively, the ports 06 and 91, the switch 83 is inits open position and the oil in the cylinders is locked with the resultthat the pistons remain stationary and hold the outer shell IS in a.fixed position. The pipe I00 between the outlet port 90 in the pumpcasing I0 and the port 95 in the valve casing 9| is provided with arelief valve I I5, the outlet port of which communicates with thereservoir II4 by way of a pipe I I8. In the event that excessivepressure develops in the pipe I08 as a result of the operator of themachine failing to return the lever I00 to its neutral position afterthe outer shell It has been swung into its discharging position or intoits normal operating position the relief valve II5 opens and the oilwhich is pumped by the gear pump flows back into the reservoir II4 viathe pipe II6.

The means 20 for supplying the outer shell I 6 with water when the outershell is in its normal operating position comprises a T fitting Ill anda pipe section H8. The T fitting I I1 consists of a pair of alignedinlet branches H9 and I20 and an intermediate outlet branch I2I and isfixedly mounted on the central portion of the bar 29 of the supportingstructure I5 so that the inlet branches are disposed in parallelrelation with the outer shell I0 and the outlet branch I2I extendshorizontally towards the outer shell. The inlet branch H0 of the Tfitting is connected to a hot water pipe I22 by way of a valve I23 andthe inlet branch I20 is connected to a cold water pipe I24 by way of avalve I25. The outerend of the outlet branch I2I of the fitting I I1 iscanted so that it is inclined upwards and rearwards and has an annulargroove I26 with a sealing gasket I21 therein. The pipe section I I3 isfixedly connected to the central rear portion of the side wall 30 of theouter shell I0 and communicates with the interior of the, outer shell.The outer or rear end of the pipe section "I I0 is canted so that it isinclined downwards and forwards, and is so arranged that it seatsagainst the gasket I 21 when the outer shell I5 is in its normaloperating position. As a result'of the manner in which the outer end ofthe outlet branch HI and the rear end of the pipe section. IIB arecanted the pipe section is free to swing with the outer shell inconnection with swinging of the latter into its discharging position.When the outer shell is in its normal operating position the pipesection II8 eiiects communication between the T fitting H1 and theinterior of the outer shell and hence water may be introduced into theinterior of the inner shell from hot water pipe l22-or cold water pipeI24, or bdth pipes.

When the outer shell I6 is in its normal operating position and it isdesired to usethe machine the door 40 is first slid upwards into itsopen position wherein it exposes the opening 39 in the front upperportion of the side wall 30 of the outer shell. Thereafter the innershell I! is rotated by proper control of the power mechanism I8 into aposition wherein the opening 50 in the side wall 45 thereof is inregistry with the opening 30 in the side Wall of the outer shell.Thereupon the door 5| for the opening 50 is slid into its open positionand the interior of the inner shell is charged with clothes and otherarticles to be washed via the openings 39 and 50. After charging of theinner shell the doors 5! and 40 are closed and water is introduced intothe outer shell by way of the fitting III and the pipe section II8.After filling the outer shell to the desired height the power mechanismI8 is set in motion by supplying current to the three phase reversiblemotor 53. During operation of the motor the inner shell II' within'theouter shell rotates back and forth for clothes washing purposes. Afterthe clothes have been washed the power mechanism III is stopped and thedump valve 38 is opened so as to discharge thewater from they interiorof the inner shell. Thereafter the door 40 is opened and the inner shellis rotated until its opening 50 is in registry with the opening 33 inthe side wall of the outer shell. Upon eiiecting registration of .theopenings 50 and 39 the door 5I is opened and effecting, through themedium of the piston rods I2, upward and forward swinging of the outershell I6 into its discharging position. As soon as the outer shellreaches such position the clothes are automatically discharged bygravity through the openings 50 and 39. .After the discharging operationthe lever I00 is swung to its fullest extent in a clockwise direction asviewed in Fi ures 7 and 10 in order to cause the oil under pressure tobe introduced into the upper ends of the cylinders 04 and the pistons65resultantly to slide downwards and effect return of the outer'shell toits normal operating position. As soon as the outer shell is swungintoits normal operating position wherein it is supported by the pins 43and the hooks 44 the operator of the machine swings the lower I00 intoits neutral or vertical position so as to discontinue drive of the gearpump I6.

The herein-described washing machine effectively and efllcientlyfulfills its intended purpose and may be operated with great facilityand speed. It is automatic so far as discharge of the washed clothes andother articles is concerned 11 and ischaracterized by the fact that thepower mechanism ID for operating the inner shell is entirely "mounted onthe outer shell and hence is always in operative or driving relationwith the inner shell regardless of whether the outer. shell is in itsnormal operating positlon'or its discharging position.
